To, all LU/wm t may. concern Be` it knowntliatl, ARNOLD; NEsCrrgf-'a citizen of the Republicv of Switzerlan'd`,"'"and resident. of asehwitzcrland, have invented new and 'useful Improvements inDeflating Pipes for the Stomachs of Riiminants (for which I have tiled applicatiOns-in Germany, May 2, 1914; Austria, May 1, 1915;

France, April 26, 1915; Great Britain, May 1o 1, 1915; Switzerland, August 23, 1917, and

Denmark, December 9, 1919), and of which the following is a full, clear, and exact speciiication.

lVith ruminant animals (such as cattle, sheep and goats) it is customary, when there is too free a formation of gases in the first stomach, or paunch, to remove the gases collected by means of flexible tubes, which are passed down the throat into the paunch, so that the stomach gases can enter o-ne endv of the tube and issue at the other end, which projects out of the mouth of the animal.

Since, however, the entry of the throat into the paunch is at the lower part of the same, it often happens that the end of the tube inserted into the paunch buries itself in the solid food in the paunch and is theree by blocked up, so that the deflating tube does not fulfil its function, or only to an insufb cient degree.

In order that the deflating tube may fulfil its function properly, it is clear that the end of the tube which enters the paunch must be in such a position that it rises into the gas-filled part above the food. In order to ensure this it has Aalready been proposed to make the tube flexible and then to lift the end when in the paunch by external means.

This arrangement is clumsy and unsafe and leads to a complicated construction, unsuitable for this kind of tube. It is also known to make the stomach tube for human beings of separate members linked together, but in human beings, where the throat opens into the top of the stomach and the anatomical conditions are quite different from those of ruminants, the tubes are only hinged to facilitate their passage down thel throat. `With ruminants, however, it is necessary for the tube to be lifted in the paunch, in order to enable the gases to be drawn ofi".

According to the present invention, the end member of the tube is pivoted to the iiexib'lemain Abodfvfthereof eccentricall'y with respectgto the` axis of the tubeand, ifftherev is-"a pluralityv of such pivoted lend, members, alongEL one and the same generatingline of' 60 tli'e'tube; the, adjacent terminal portions ofr said?` parts ofi the tube arek so shaped as to allowy of pivotal movement: of saidfendlmem'-v ber (or members) lout ofthe axis only in a direction opposite to the pivot connection side. Inthis manner the end member (or members) of the deiiating tube is automatically lifted in the paunch, since, if the tube is inserted with the pivots on the underside, the end member (or members) of the tube, on striking an obstruction vin the paunch,

is automatically turned upwards owing to al turning moment relatively to the pivot.

The invention is illustrated in the accompanylng drawings by way of example, Fig. 1 showing a dei'lating tube in use on a cow; Fig. 2 showing the tube broken into three sections.

The deiating tube according to the present invention consists of a rigid handle a, a flexible central part or main body b which cannot, however, rotate on itself, and a similar terminal part c to which two rigid end members d, f are freely pivoted. Of these two the end member l is pivoted to a ter- 85 minal `on the part c, and the end member f is pivoted to the member d, in such a many ner that the pivots are eccentric to the axis but in the same generating line of the tube. On one side of the connection pivots, the end members l and are provided with an abutting face or stop indicated at h in Fig. 2, so as to be prevented from overturning downwards out of the straight line; however, said abutting or stopping means could also be provided at any other convenient point. On the opposite or upper side, the said end members are bevelled at i (Fig..2) so that they can be inclined to the side or turned upwards with respect to the axis ofthe tube.4

This change of direction of the members d, f occurs automatically on inserting the tube in the paunch. When inserting the tube, care must be taken that the pivots are une derneath. If these members strike against an obstruction in the paunch, they automati! cally turn upwards as shown in Fig. 1, and the member f finally assumes an upright position, in which it allows the stomach gases to pass o through the opening g in the tube 1 and so pass out through the tube.

The flexible part of the tube consists, in,

the construction shown, of a comparatively stiff spirally Wound steel strip, but it may also be constructed in other Ways. The front pivot member j is smoothly rounded oli' at its lree end, in order to prevent any injury to the internal organs. The various parts of the throat tube are screwed together in the usual manner, so that the tube can be taken apart for transport purposes. The sections may, however, be connected together in any other manner. li necessary, the openings at the pivots may be covered over and the parts may be pivoted together by pliable connecting` parts instead of by ordinary hinges, but these parts must always lie in the same generating line. The ilexible part of the throat tube may be made of metallic tubing pressed lat.
